I hand load to two levels. A 115 grain lead bullet at about 850 ft/sec is one level and the other level is a 100 grain jacketed at a much higher velocity using H110 or 2400 powders. I'm not going to give the loads or velocity for the top tier, but if you don't handload, Buffalo Bore has a +P loading which launches a 100 grain bullet at around 1200 ft/sec from shorter barrels. I would not use the higher velocity loads in the H&R revolvers, or the small frame (undercover size) charter arms revolvers. For the larger charter arms bulldog size frame, I would probably ask charter arms about the use of the buffalo bore ammunition.
The lower level loads are perfect for the recoil sensitive shooter, or plinking, or as a trail gun. One person on this forum characterizes the .32 H&R as a reloadable .22 rimfire and I agree with that characterization for the plinking level loads. As a defensive cartridge, I occasionally rotate my "nightstand" gun, and my .32 H&R, Ruger SP-101 sometimes gets a turn. With the heavier loads, I do not feel helpless and I sleep soundly.
As for what I think of the cartridge: I understand the power constraints for the H&R revolvers, but I wish the cartridge was a little more powerful but less powerful than a .327 federal.
